Al... it's not a 'trial' in the sense of a court. In the judicial system, there are clear rules and a citizen's jury. Impeachment sends the case to the Senate... which conducts itself however it decides to... using rules under the control of McConnell. When Nixon was almost impeached, most senators were already convinced of his guilt.. they told him he had only a few votes, so he resigned.
   When Clinton was impeached, the senate discussed rules and voted 100-0 on how the 'trial' would be handled, and he was not convicted.
Now, there is an entirely different attitude among Republicans, and they are in the majority with at least two promising that there is NO chance of a conviction of Trump. It is **almost** impossible that anything will change while McConnell is able to fill courts with conservative judges... so there is no chance of getting 2/3 majority needed to remove Trump.

Right now, the Democrats are in a holding pattern about when.. and if... to send the case TO the Senate. The impeachment does not expire...ever... so if the senate remains a lost cause, it is possible to just wait and see in Trump can actually get re-elected... then send the case over for trial in a year.

There's no easy answer... the deck is stacked and only the voters can remove this &@$$%^!#...
